Abstract:

Integration and test of the GEMINI instrument package. Most of the work performed under this task supported development of the GEneralized Multi-wavelength INfrared Imager GEMINI for the Maui Space Surveillance Site. GEMINI, not to be confused with the National Science Foundations Gemini Telescopes Project, is a one-of-a-kind sensor package built for USAF Space Command operational use in conjunction with its space object identification SOI mission. GEMINI hosts a variety of sensors for use with several algorithms for reconstructing high-resolution satellite and astronomical images from data degraded by atmospheric turbulence. The first GEMINI operating mode made available to Space Command delivers high resolution images using a speckle imaging technique. Schafer contributed to the project by implementing and developing parallel speckle imaging recovery and calibration algorithms and by designing computer simulations to model real-world detector effects and predict available resolution. Schafer also conducted an observational evaluation of the speckle imaging algorithm. A distinctive feature of the GEMINI data acquisitionreduction system is the provision for near real-time NRT video feedback of reconstructed imagery to the GEMINI operator. NRT feedback allows the operator to select camera exposure times and optical filters based on the visual quality of reconstructed data. These operating parameters can thus be optimized while data is being acquired, potentially eliminating the need for subsequent observations of the same object. For example. raw image data of a bright satellite can yield a poor reconstruction if most of the light is concentrated in a strong, localized glint. Selection of a different filter may reduce the glint effect in the reconstruction, which would be apparent to the operator using an NRT imaging system.
